Hey, I own a 89' HF and all of a sudden my mileage is getting lower and lower, its down to about 24 MPG on a stock motor, the car hasnt seemed to be running differently or the idle isnt raised, anyone have any advice?

 

Have you recently changed your oil, air filter, pcv valve, spark plugs, spark plug wires, distributor cap, and your distributor rotor? Have you recently as well made an inappropriate comment about your car that it could use against you as it withholds gas mileage?

 

how bout 02 sensor i know would give u shitty milage.so would clogged or drity fuel filter.
